One of the big remaining reasons people use Mudlet and its mapper is that it can be used to chase people after using location abilities.
That's a pretty essential thing for a lot of combat and is one of the few areas where there's still a pretty massive advantage to using Mudlet over Nexus.
We already have a personal landmark system - could we get a personal landmark tied to location abilities that autosets to the room your last room-revealing location ability revealed?
So if someone does ETHER SEEK TAEL and it works and shows the room name, that overwrites a magic personal landmark called TARGET to the room that ETHER SEEK revealed and you can then WALKTO TARGET to try to walk to that room.
If you then do ETHER SEEK TAEL again, it just updates the landmark to whatever room that use reveals and you can WALKTO TARGET to get to that room.
If you do FARSEE TAEL and you're in the area so it reveals the room, it updates the landmark to whatever room it revealed and you can WALKTO TARGET to get to that room. If it reveals an area, it can either set the personal waypoint to that area (I know you can WALKTO <area name>, but I'm not sure if it's possible to set an area as a waypoint) or it should just leave the TARGET landmark alone (i.e., failed uses of location abilities shouldn't overwrite or blank out the TARGET landmark).
